Directly supplying Chicago’s industrial buyers with certified progressive stampings, rotary slitting knives, ultra-thin diamond cutting discs, and custom punch dies.
As North America's premier manufacturing and logistics engine, Greater Chicago—encompassing key industrial belts such as the O'Hare Industrial Corridor, Elgin, Schaumburg, Rockford, and the Calumet Industrial District—demands strict metallurgical integrity, micrometer-level repeatability, and cost-effective volume manufacturing.
Unlike generalist metal fabricators, our engineering operations integrate complete in-house die design, progressive stamping tool build, and high-tonnage hydraulic drawing under one roof. For Chicago OEM buyers seeking certified alternatives to local high-cost supply chains, we supply mill-certified stainless steel, carbon steel, and specialized alloy stampings with zero third-party tool markup.
Strategically located near major ocean freight corridors with seamless connection to Midwestern intermodal ramps (including Chicago CN/CPKC rail terminals and O'Hare cargo gates), we provide complete export documentation—including Mill Test Reports (MTR), Certificates of Origin, and accurate US HTS classification (HS 7220.90 / HS 7326.90).
Our precision stamping, deep drawing, and rotary slitting blade manufacturing serve critical Tier-1 and OEM applications across Illinois and the broader Great Lakes Region.
High-volume stamped brackets, deep-drawn sensor housings, structural shims, and terminal connectors engineered for Midwest automotive supply chains and EV platform integration with tight burr tolerances.
Ferritic stainless steel (EN 1.4016 / SS 430) induction discs, deep-drawn vessel shells, and custom perforated inserts for commercial kitchen equipment and consumer appliance brands operating across Illinois.
Tungsten carbide slitting knives, rotary industrial blades, and heavy-gauge structural stampings built to withstand severe friction, shock load, and continuous cutting duty cycles in industrial machinery.
Hot-pressed ultra-thin continuous rim turbo blades and diamond-brazed saw discs for precision cutting of ceramic tile, porcelain, granite, and masonry across Chicago construction and infrastructure projects.
Custom-sized round slitting circular knives and punch circle cutters designed for high-speed plastic film converting, corrugated container manufacturing, and flexible packaging lines in Chicago industrial parks.
Deep-drawn electrical boxes, stamped fan shrouds, louvers, and corrosion-resistant stainless lids manufactured to drawing specifications with uniform wall-thickness distribution.
Understanding how Midwestern procurement managers are optimizing total cost of ownership (TCO) through strategic Asian export partnerships.
Domestic tooling lead times in the US Midwest often exceed 20–24 weeks with exorbitant die charges. Chicago procurement teams leverage our in-house die development capability to shorten prototype-to-production cycles down to 4–6 weeks while cutting tooling expenditures by up to 60%.
Modern quality systems require comprehensive lot-level traceability. Every shipment exported to Chicago buyers includes heat-specific Mill Test Certificates confirming chemical composition (Chromium, Nickel, Carbon balance) and mechanical yield properties.
With rising raw material volatility, buyers are shifting toward SS 430 (EN 1.4016) for magnetic permeability in induction appliances and automated machinery sensors. Our deep-drawing processes ensure zero micro-cracking even under aggressive draw ratios.
Modern progressive die engineering minimizes scrap web ratios during high-speed blanking. Our state-of-the-art power press operations reduce energy consumption per part while enforcing 100% recycling of raw metal off-cuts.

Founded in 1974, our enterprise operates dual manufacturing plants—primary buyer coordination & tool room in Mumbai, Maharashtra, complemented by our high-capacity production facility (Mammal Industries) in Sarigam, Gujarat. We engineer custom stamped parts, deep-drawn bowls, induction plates, and industrial circular blades strictly to client drawings with zero compromise on quality.
Custom progressive dies, compound stamping tools, and draw dies engineered internally. Your proprietary component design stays 100% under our secure intellectual property protection.
With operational facilities across Mumbai and Sarigam (Gujarat), we absorb peak-season production volume surges with reliable lead times and zero delivery interruption to US ports.
Located just 35 km from JNPT container terminals, providing direct ocean freight routes to Port of Chicago, Chicago intermodal rail hubs, and regional Midwest distribution centers.
Addressing key commercial, technical, and shipping questions for seamless international procurement.
For custom stamped components or circular slitting blades, tool design and first-article qualification sample delivery take approximately 2 to 3 weeks. Once production samples are approved by your quality team, ocean freight transit from JNPT Port to the Port of Chicago / Chicago Intermodal Rail Terminal typically ranges from 28 to 35 days under FOB, CIF, or DDP terms.
Induction hobs generate heat via magnetic eddy currents. SS 304 is an austenitic stainless steel and is paramagnetic (non-magnetic), meaning it will not heat up on an induction burner. SS 430 is a ferritic stainless steel (EN 1.4016) with strong ferromagnetic permeability. When stamped and impact-bonded or welded to aluminium pan bodies, it allows standard cookware to function perfectly on induction surfaces while maintaining high corrosion resistance.
Yes, absolutely. Every single batch dispatched from our plants is accompanied by certified Mill Test Reports (MTR) confirming chemical composition (heat code level) and physical mechanical properties. We also provide full CMM dimensional inspection sheets and surface roughness reports aligned with ISO and US OEM quality standards.
We provide accurate export documentation to ensure seamless clearance at US Customs in Chicago ports. Typical classifications include HS Code 7220.9090 for stainless steel circle blanks, HS Code 7326.9099 for general stamped metal parts, HS Code 8208.8000 for industrial slitting circular knives, and HS Code 6804.2200 for diamond cutting discs and saw blades.
Tooling developed for client-specific engineering drawings remains 100% the property of the client. We offer amortized tooling options or direct die purchase. All custom dies are maintained and preserved in our secure tool room with routine preventative maintenance at zero extra charge for the operational lifetime of your product contract.
MOQs depend on part size, stamping press tonnage, and material coil setup. For standard continuous rim diamond saw blades or stock circle blanks, MOQs start as low as 500 to 1,000 units. For specialized custom progressive metal stampings, we flexible-structure production runs to support initial sample validation, pilot builds, and scheduled monthly container volumes.
Yes. As an established OEM contract manufacturer, we offer full white-label production. Brand logos, part numbers, lot codes, and alignment notches can be directly stamped, embossed, or laser-etched onto your components during press operations without requiring secondary handling.
